KEYLESS LOCK.

Specification of Letters Eatent.

Patented Mar. 29, 1921.

Application led .Tune 2, 1920. Serial No. 385,926.

To all whom it may concern:

Be it known that I, MEADE 1WILDRICK, a citizen of the United States,residing at- Savannah, in the county of Chatham and State of Georgia,have invented certain new and useful Improvements in Keyless Locks; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention relates to improvements in keyless locks, and it isintended to A yprovide a mechanism which may be used in combination withlocks of standard construction, or of special design, in which thenecessity for a key is done away with.

According to my invention I provide a combination wheel arrangement inconnection with. a locking bolt and other details,

whereby the lock may be set atany given combination and can be operatedonly by a person knowing said combination and understanding the mode ofoperation of the scribed in the specification.

shown in Fig. 4 as seen from the left of said ligure.

Figs. 6 to l0 show the lock as applied to the door of a house, safe, orthe like;

Fig. 6 being a front elevation of the lock, parts being broken away.

Fig. 7 shows a section along theA broken line 7 8 of Fig. 6, and lookingin the direction of the arrows, but with the lock in the open orunlocked position.

Fig. 8 is a similar view to Fig. 7, but shows thelock in the closed orlocked position.

Fig. 15 shows a section along the line 15 15 of Fig. 14, and looking inthe direction of the arrows,

' cured thereto as by means of the bolts a2.

' in the 4frame of the bearing block This housing comprises twochambers, one, the larger chamber, A for the locking bolt andcombination wheels, and the smaller chamber A2 for the locking platecarried by the hasp. The housing is transversely slotted, as at a3, topermit the insertion of the said locking plate, and as at a4 to disclosethe outer numbers of the combination wheels.

B represents the hasp which is hinged as,

at b to the plate D carried by the plate D, which plates D and D aresecured to the receptacle X in any convenient way, as by,

means of the rivets C. The hasp is shown in the closed and lockedposition in full lines in F ig. 2, and in the open position, in dottedlines in said figure, and it is also shown in the closed and lockedpositionin dottedlines in Fig. 1.

The means for locking the hasp comprise i the locking plate E,preferably slotted at each end, as at e", and provided with a boss.

e adapted to project into a socket 6 in the hasp. The plate E isconnected by means of the stem Vto the handle E2 which has an annularbottom e?. This steml E is rigidly secured tothe locking plate E in anyconvenient way, as by means o f the nut e', and the connection is suchthat when the handle E2 is turned the locking plate E will l -also beturned.

F represents the locking bolt which has attached thereto any convenienthandle, such as the knurled head f. This locking boltfis provided 'withthree axial 'ribs f', f2 and f3, and with a. downwardly projectinglocking bar F which includes the vertical legs f4 and f5, with a slotbetweenthem, andl the cross piece f6 at the bottom. These ribs f', f2and f3 slide in grooves g,Gy2 and g3 mounted in the lock casing. Therear fa'ce of this frame is cut away, as at g, to permit ,move- Ilpentof the locking bar F', as `shown in evolubly mounted on the shaft I inthe lock casing are a plurality of.:` combination wheels of which I haveshown three, H, H andIIZ, but there may be two or more of thesecombination wheels if desired. 4 I prefer to use three as affordingsufficientA protection for all practical purposes without unnecessarilycomplicating the mechanism,

but two may be used if desired. These combination wheels are allpreferably of similar construction, one of which is sho-wn in detail inFigs. l and 5, in which the body of the wheel is provided with a seental slot ko just inside the radial slot L. Ahe periphery of the wheelis preferably grooved, as at L, and rovided with screwthreaded socketsk2. he segmental strips K are mounted in these grooves, bearing numbersone to nine, as shown in Fig. 5, and these strips are secured in placebycclamp .screws L engaging in the corresponding sockets h2.

In order to vary-the combination, it will be sufficient to move the saidscrew L and shift the segmental strips K around through adistancesufficient to change the reading of the exposed figures when the slot hregisters with the cross piece f6 of the locking bar F A few only ofthese numbers on each wheel will be exposed in the openings a* of the"lock casing as indicated in Fig. 1. It Awill be noted that when thethree wheels H, H and H2 are turned with their radial slots `v indicatedin dotted lines in Fig. 2, but if any one of these wheels is turned sothat its slot h does not register with the cross piece f6, then it willbe impracticable to pull the locking bolt to the front.A It will also beobvious that it would be very difficult, in fact impossible, for allpractical purposes for anyone not familiar with the combina, tion to setthe three combination wheels so that all three slots h willsimultaneously register with the cross piece f6 of the locking bar F.

Assuming the parts to be inthe position shown inv full lines in Fig. 2,in order to release the hasp it will be necessary to see that all threeof the wheels have their slots l1. registering with thel cross piece f6.v bolt being in the position shown in full lines, itsrib f will engagein one of the notches @o of the locking plate E carried by the hasp. Nowif the bolt be pulled -forward to' the position shown in dotted lines.in Fig. 2, the c'ross piece f6 will pass through the slots k in therings, and the rib f will move The -clear ofthe notch 4e0 permitting thelocking l plate E to be turned by means of the handle E2. l

When thislocking plate/E is turnedY through a right angle from theposition shown in Figs. 1 and 2, it will register withthe `transverseslot a3 in the lock casing, k'and the hasp may be swung' clear to thelposition.

be Apointed out.

terasse inside at any time, but can be opened from the outside only whenthe combination wheels are set at the proper position for permitting thesliding of the locking bolt, as already described in connection withFigs. 1 to 5.

In'the modification shown in Figs. 6 to 10, M represents al suitablemetal casing mounted in the door X in any convenientl way,l which casingpreferably comprises a housing M and a cover or rear plate M2 secured tosaid housing in any convenient way, as by means of the screw bolt-s m.The lock- .ing bolt F is similar to that already described withreference t0 Figs. l to 5, exceptthat it may be more convenient forpurposes of assembly to fasten the -knurled head f to the main body ofthe locking bolt by means of a stem Fo and nut f.

In this modification the v combination wheels H, H and H2 areconstructed and coact with the locking bolt precisely as alreadydescribed with reference to Figs. 1 to 5. Slight changes are made,however, in the devlce cont-rolled by the combination lock alreadydescribed,

N', represents the front knob of a door, carried b v the stem N, therear end of said stem preferably being provided with a flange or setcollar 1t to which the. stub shaft N2 is connected, which stub shaftcarries a downwardly projecting plate or rib N3, slotted as at n3 toregister with theupper rib f" on the locking bolt F when said loc-kiIng` bolt is pulled forward, as shown in iig. 8. c

In Fig. 7 the locking bolt is shown ,in the position for releasing thefront door knob, but in Fig. 8 it is shown in the. position for lockirgthe same. There itv is desired to open or close the door from one sideonly. as with safes, vault doors, or the like. a single knob with stemwould sufce.

as ust described; but in order that the door` may be freely opened fromwithin some suitable arrangement should be provided for vshooting theordinar7 bolt O used in holding the door closed. Such an arrangement isshown in detail in Figs. 6 and Lin which the bolt O is chambered. as. ato.to receive the coil spring O normally tending to push the said boltoutward to the position for holding the'doo1",closed. The spring 0mounted in the bolt may bear against the guide lug O2 attached to thelock casing. as

at o2. and the outward travel of the saidv mental teeth p on the housingP. carried 'by the stem lP to which the inside door knob P2 is rigidlyattached. 'This housing is chambered as at p0 to receive the end of thestub and which will now .inserted in the casing shaft N2 which carriesthe spring-impressed pawl Q engaging with the ratchet teeth p' on .theinner wall of tle chamber p0, as shown most clearly in Fig. 10. By thisarrangement the knob P2 may be used to slide thev bolt O in eitherdirection, irrespective of whether the combination lock is on or not.

In order to operate or open the door from the front, it will benecessary to have the slots h in the various combination wheels so setthat the cross piece f6 may be slipped from the position shown inFig. 8to that' shown in Fig. 7. Yhen the parts are in the position shown inFig. 7, the door may be opened with equal facility from either the frontor the rear; but if the bolt F be in the position shown in Fig. 8, andany one. of the combination wheelsA be turned so that its slot does notregister with the travel of the cross piece f6, then it will beimpracticable to open the door from the front.

In the arrangement shown in Figs. 11 to In this modification the lockingbolt is I shown as built up ofa stem F0, carrying' the knob or' handle fand thesleeve F 2, car-y rying the side ribs #and f3, and the lockingbar' F, ksimilar to the. locking bar already described. This sleeve F2is secured to the stem' F o. by mea-ns of a set screw f7 105 which maybe'insierted through the opening 87 in the housing block S, which blockis rIhe casing R, may be provided with an internally pro? jecting'rib r,and the block S may be Secured thereto by means of a screw r', see Fig.111 Thus the casing R and the housing.block.S effectually mask all ofthe parts, except the shackle T and the exposed portions of thecombination ywheels which project into the slots fr provided in thefront of the casing R.

. rI`he housing block- S is provided with chamber s to receive the -armt of the shackle `T. whicl arm is preferably provided with a flange t toprevent it from being withdrawn from the casing R. as shown in,` Fig.11. The shackle is U-shaped in cross section. and the two legs areprovidedl on op- -posite sides with the notches t2 and t3 to engage theribs f'f' and f3 of the locking bolt. when the shackle is in the closedand locked position, as shown in Figs. 11 and 12.

It will be obvious that unless the combination wheels are so setthattheir slots k will all register with the cross piece f6,

then the bolt F cannot be pulled forward and the shackle will be held inthe locked position. When the combination wheels are so set that itsslots h all register with the cross piece f6, then the locking bar F maybe pulled forward, causing the ribs f2 and f3 on the locking bolt torelease the shackle and permit it to be drawn to the position shown indotted lines in Fig. 11, and then rotated about itsleg t if desired.

In the modification shown in Figs. 14 to 17, I have shown my inventionas applied to locking the various electric circuits of an automobile. Urepresents the casing, preferably flanged at its front, as at u, andsecured to the instrument board, not shown, of the automobile Thiscasing is chambered, as at U9, and the rear end is closed by aninsulating` disk U carrying the binding posts V and V connectedbysuitable conductors to the source of electricity carried by thevehicle,l not shown.

These binding posts are shown inFig. 16, and one of them only is shownin F igl. 15.

ounted in this casingis an insulating -l bearing block U2 in which thelocking bolt F3 is slidably mounted. This locking bolt sible for anexpert to turn these wheels, note carries two side ribs f2 and f3adapted to engage in the teeth L02 and w? on the segments carried by theshafts fw and fw, on' which shafts are fastened theA switch arms W andW', respectively, which make contact-With the contact points foroperating the various devices carried by the car; v l have shown in Fig.17 the two switches W and W in the off position. By turning the switch Wto make contact with the point y the circuit is closed through thebinding post Y, which may control, for instance, the circuit for theside and rear lights. The binding post Y carries the contact point ywhich ymay control the auxiliary head and the rear lights; andthebinding post-Y2 may carryI the contact point 'y2 for controlling thehead and rear lights.

The switch W may be used to control the circuits through the bindingposts Y3 andthe contact g3 from theV battery when the magneto is not inoperation, and through the-binding posts Y4 and the contact point y4when the magneto is on.

The cross piece f6 carries', insulated there-- from, the contact strip`Z, see Figs. 16 and 17, which makes contact from the main binding postsV and V and closes and fprovided with thumb lugs breaks the circuitaccording to whether the p locking bolt is in the rea-r positionV shownin full lines in Fig. 15, or is moved'more or less forward to break thecircuit. i

The switches W and W are preferably or handles W9 -for convenience inoperating the same.

It will be obvious that thebolt F3 can-l not be moved forward unless theradial slots l1, of all thel combination wheels register with the crosspiece f, and that yif any one of these wheels be turned so'. that itsslot will not register with saidv cross piece thelocking'bolt F3 cannotbe moved axially.

In the operative position, the locking bolt F 3 is shoved inward,`asshown in Fig. 15, and when in the locked position the said locking boltis drawn outward until the ends of the ribs f? and f3 engage the rearwall of the front face of the casing7 at which time the cross piece f6will have been drawn into the segmental slot hf in all three of thecombination wheels.

Now if any one of the combination wheels be turned through an angle, thelocking bolt will be held in the withdrawn position, and all of theelectric circuits will be broken.

The above described contact strip Z may be made independent of thecontacts Y, Y2 Y3 and Y4 if desired.

It will be`` noted that in all of the con-A structions hereinbeforedescribed the set screws L roject somewhat and will prevent -thecombination wheelsfrom being turned far enough to expose the slots kthrough.

the corresponding recesses in the front of tliexlock casing, otherwiseit might be pos- `If it b e .desired the various combination wheels mayhave the numbers thereon shown in luminous paint so that the,combination may be set at night without the use of arti-. l 'iciallight.

While I have illustrated the various combination wheels provided withindicia in the form of Roman numerals, it will be obvious that theletters of any language may be substitutedfor the Roman numerals, or, ifpreferred,- designs or hieroglyphs may be used on the variouscombination wheels, and

theseJ indicia may be varied from time to time by simply shifting theadjustable strips onthe periphery of any one or more of the variouscombination wheels.

It will be noted that all ofthe various devices hereinbefore describedpossess the following elements in common (1) A sliding locking boltcarrying ribs izo locking bar having a transverse cross piece.

(2) A series of combination wheels, each provided with a segmental slotopening into `a radial slot, and that unless all of the wheels are setwith the radial slot registering with the cross piece, it will beimpossible to operate the device.

(3) Therey is a third device locked'or re- I leased bythe slidinglocking bolt, and the movement of the locking bolt is .controlled by theposition of the combination wheels aforesaid.

lVhile I have shown the invention as applied to the various purposeshereinbefore' described, it will be obvious that it may be used in agreat many other relations which are not herein described; and I do notmean to limit the invention to any specific use.

It will also be obvious that various modiications might be made in theconstruction,

combination and arrangement of parts which could be used withoutdeparting from the spirit of my invention; and I do not mean to limitthe invention to such details except as particularly pointed out in theclaims.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is l.
